Osteospermum plant named ‘Sunost1101’

ABSTRACT

A new and distinct cultivar of  Osteospermum  plant named ‘Sunost1101’, characterized by its upright, outwardly spreading and mounding plant habit; freely branching growth habit; freely flowering habit; daisy-type inflorescences with purple-colored ray florets; good garden performance and tolerance to high temperatures.

Botanical designation: Osteospermum ecklonis.

Cultivar denomination: ‘SUNOST1101’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Osteospermum plant, botanically known as Osteospermum ecklonis, and hereinafter referred to by the name ‘Sunost1101’.

The new Osteospermum plant is a product of a planned breeding program conducted by the Inventor in Odense, Denmark. The objective of the program is to create and develop new Osteospermum plants with compact and uniformly mounded plant habit, freely flowering habit and attractive inflorescence coloration.

The new Osteospermum plant originated from a cross-pollination by the Inventor in May, 2008 of Osteospermum ecklonis ‘Sunny Felix’, disclosed in U.S. Plant Pat. No. 17,419, as the female, or seed, parent with a proprietary selection of Osteospermum ecklonis identified as code number 05.50.002, not patented, as the male, or pollen, parent. The new Osteospermum plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled greenhouse environment in Odense, Denmark in June, 2009.

Asexual reproduction of the new Osteospermum plant by terminal cuttings in a controlled greenhouse environment in Odense, Denmark since November, 2009 has shown that the unique features of this new Osteospermum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Osteospermum have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sunost1101’. These characteristics in combination distinguish ‘Sunost1101’ as a new and distinct Osteospermum plant:

-   -   1. Upright, outwardly spreading and mounding plant habit.     -   2. Freely branching growth habit.     -   3. Freely flowering habit.     -   4. Daisy-type inflorescences with purple-colored ray florets.     -   5. Good garden performance and tolerance to high temperatures.

Plants of the new Osteospermum differ primarily from plants of the female parent, Sunny Felix’, in ray floret color as plants of ‘Sunny Felix’ have white-colored ray florets with a violet blue-colored spot.

Plants of the new Osteospermum differ slightly from plants of the male parent selection in ray floret color.

Plants of the new Osteospermum can be compared to plants of the Osteospermum ‘Sunny Xandra’, disclosed in U.S. Plant Pat. No. 19,634. In side-by-side comparisons conducted in Odense, Denmark, plants of the new Osteospermum differed from plants of ‘Sunny Xandra’ in the following characteristics:

-   -   1. Leaves of plants of the new Osteospermum were elliptic in         shape whereas leaves of plants of ‘Sunny Xandra’ were more         rounded in shape.     -   2. Inflorescences of plants of the new Osteospermum had fewer         ray florets than inflorescences of plants of ‘Sunny Xandra’.     -   3. Plants of the new Osteospermum and ‘Sunny Xandra’ differed         slightly in ray floret color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs illustrate the overall appearance of the new Osteospermum plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Osteospermum plant.

The photograph at the bottom of the sheet comprises a side perspective view of a typical flowering plant of ‘Sunost1101’ grown in a container.

The photograph at the top of the sheet is a close-up view of a typical flowering plant of ‘ Sunost1101’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs, following observations and measurements describe plants grown during the summer in one-gallon containers in an outdoor nursery in Bonsall, Calif. under cultural practices which approximate those generally used in commercial Osteospermum production. During the production of the plants, day temperatures ranged from 27° C. to 35° C. and night temperatures ranged from 16° C. to 20° C. Plants were pinched one time and were twelve weeks old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2007 Edition, except where general terms of ordinary dictionary significance are used.
